Using disqus API for comment system on website

Hi everyone,

I want to develop a comment system for my website. site is developed using ASP.NET 3.5. From my research, I have got an option for disqus API for that. But I am not getting any proper tutorial or sample application for this and not being clear about how to use this API for adding comments on my site. If anyone aware of this, can you please suggest some sample code or source where I can get some help about this.

Thanks,
Suhani.
